Full Dress

The dress worn on occasions of ceremony. If a man has no
special costume, his “full dress” is a suit of black, open waiscoat,
swallow-tailed coat, white neckcloth, and patent-leather boots or
half-boots. Academicals are worn in the Universities and on official
occasions; and full military dress is worn when an officer is on duty,
at court, and at official fêtes, but otherwise, “evening dress”
suffices.
